Decent; it starts off with all the limitations of castle-style levels (i.e. small, pokey green rooms), and one of the early courtyards has a lift puzzle that's so easily bypassed you might not even notice it was there. The battle that ensues is exciting, but I hated the "stepping stones" section. It looked nice, but it's irritating to play, even if you allow for source port jumping. The level ends after that with a small fight that you can run around.
